Authorities say a skateboard-clutching bandit flashed a gun at a San Diego bank teller, stuffed money in his backpack and fled.

Police and FBI investigators say no one has been arrested for Monday’s heist at a Comerica Bank. The thief’s face was covered by a green paisley bandanna and his beanie, sweat shirt, gloves and pants were black, the Los Angeles Times reports.

The FBI released a photograph showing the thief holding his skateboard.
